Rabbit Board Timer B Library:

Z-World does not provide a library for the timer B of the
Rabbit processors. The documentation and samples they provide
do not help on how to implement your own timer routines.

This library implements a programmable timer interrupt. The
library handles the timer setup and interrupts. When the desired
period is reached, a user function is called. The features of
the library are as follows:

Timer periods from every 15us to 1500 seconds.

User function can be in 'C' or assembly.

Low overhead (Library ISR is written in assembly language).

Easy setup, just one call to set period.

Timer accuracy can be determined at run time.

Timer can be disabled or reconfigured for a different period.

No assembly coding necessary.

Even if you don't use the library, it is useful as a good
example on how to setup and use the timer B.

Rabbit sscanf() Library:

Seems Z-World again missed the boat. This is really a standard
'C' function, but it is missing from their libraries. This library
implements the sscanf() function and a few others that are missing.

Of course, the Softools Compiler already
has this (and much better stdio support.)

The DC library can be downloaded here:

Standard 'C' malloc() and free():

In embedded systems, use of malloc() and free is discouraged
due to the possibility that the system may run out of memory.
But sometimes it is desired, especially if porting code from
another system. This library implements a simple memory manager
using a block of root code space. It does not support xmem. Included
is a debug feature that will report if the bounds of a block
of memory are overwritten.

Not Needed for Softools.

The DC library can be downloaded here:

Rabbit Board IP Locator:

This is an example on how to Configure the Rabbit TCP/IP stack
at run time. It also provides a way to find the Rabbit Boards
current IP. A PC utility will search for boards and allow the
user to configure the IP, Mask and Gatway address or use DHCP.

CoExec Multi-tasking exec for Softools and
Dynamic C:

This is a simple cooperative task switcher originally written
for Softools. Each task has its own stack, allows some preemption.
Fast task switching. Also supports far task stacks to save root
code space.

Dynamic C costates/cofunctions have proven unreliable in recent
compilers. To get around these problems, CoExec was ported to
Dynamic C with great results. Programs now run faster, with less
code and are far more reliable.

New!

LZ77 and CRC16 Library for SofTools.

LZ77 is a simple compression algorithm. It is the method used
by the Z-World ZCompress. This library can decode data compressed
using this algorithm. The compression is better than the ZW implementation.
These compressed files can be stored on a file system or included
in a user program via #pragma init_file.

Store compressed files in flash with #pragma init_file and
decode them. Includes source to a fast CRC16 algorithm.

Not Applicable

Fixed point library for Softools. Supports real numbers
from -32678.99999 to 32767.99999.

No real documentation at this time, just the lib and a sample
app.
